A tunable optical delay line(ODL) featuring high switching speed and low optical loss is highly desirable in many fields. Here, based on the thin-film lithium niobate platform, we demonstrate a digitally tunable on-chip ODL that includes five Mach–Zehnder interferometer optical switches, four flip-chip photodetectors, and four delayline waveguides. The proposed optical switches can achieve a switching speed of 13 ns and an extinction ratio of34.9 dB. Using a modified Euler-bend-based spiral structure, the proposed delay-line waveguide can simultaneously achieve a small footprint and low optical propagation loss. The proposed ODL can provide a maximum delay time of 150 ps with a resolution of 10 ps and feature a maximum insertion loss of 3.4 dB.

Introduction: The expected health effects of circadian rhythm are of major public health interest. However, it remains unknown the association between weakened and/or disrupted circadian rhythm and gastroesophageal reflux disease. This study aims to examine rest-activity rhythm characteristics in relation to gastroesophageal reflux disease in a large population-based ***: This prospective study used data from the UK Biobank. Rest-activity characteristics were derived from extended cosine models using 7-day actigraphy. Cox proportional hazard regression, with time since accelerometer wearing time as the start of follow-up, was used to model the associations of circadian disruption and gastroesophageal reflux ***: We found that compared to those in the highest quintile of amplitude, a measure of the strength of the rhythm, participants in the lowest quintile(i.e, those with the weakest rhythmicity) were 1.16 times more likely to develop gastroesophageal reflux disease(OR Q1 vs. Q5 1.16(1.07, 1.28)). Similar patterns were observed for other rest-activity characteristics, including mesor(1.17(1.06, 1.28)), and delayed acrophase(1.09(1.00, 1.19)). No significant associations between F statistic and gastroesophageal reflux disease were ***: Our findings support an association between weakened and/or disrupted rest-activity rhythms and gastroesophageal reflux disease among the general population.

目的探讨该市毛线及粉尘厂工人群体肺功能及其与空气污染的相关性分析。方法入选519名毛线厂(毛线组)及503名粉尘厂(粉尘组)工人(统称研究组),并以326名健康体检者作为对照(对照组),采用呼吸仪进行肺功能检测。对以上厂区及非厂区社区进行空气采样,进行二氧化硒(SO_2)、二氧化氮(NO_2)、二氧化硅(SaO_2)、棉尘及其他PM2.5物质浓度测定,并分析肺功能与上述五者浓度的相关性。结果与对照组比较,粉尘组、毛线组工人的肺活量(VC)、用力肺活量(FVC)、最大通气量(MVV)、第一秒用力呼气容积(FEV1.0)及第一秒用力呼气量与用力肺活量比值(FEV1.0%)均降低(P0.05),而两组间的MVV、FEV1.0及FEV1.0%差异均有统计学意义(P0.60,均P<0.05)。结论该市部分厂区空气污染较重且工人肺功能受损;毛线厂区棉尘含量高、粉尘厂区SO_2含量高,可能是该市毛线及粉尘厂工人群体肺功能受损的主要因素。

远程工作因其对于员工个人、组织和社会具有减少交通、降低成本、平衡工作与家庭、有利环保等优势,而成为近十多年来被越来越多组织接受的一种新型工作方式,并得到社会学、经济学、法学和管理学等学科领域学者的广泛关注,然而其并没有像人们预计的那样会随着信息网络技术的快速发展而广为流行,实施过程中的各种障碍逐渐显露出来。本文从远程工作的员工需求拉力与组织供给推力的双力概念模型出发,从员工个人、岗位性质和组织管理三个方面梳理了影响远程工作计划实施的因素,构建出员工自我抉择分析模型和组织挑选分析模型,并对制约远程工作发展的因素提出管理对策与建议,指出未来可能的研究方向。
